PoTATo- DIGGER.

SPECIFICATION forming part of Letters Patent No. 346,819, dated August3, 188,6.

Application tiled October 7, 1885.

To all whom it may concern;

Beit known that I, GHAnLEs W. KATTELL, a citizen of the UnitedStates,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Potato-Diggers, of which the following isa specification.

This invention has for its object to provide novel mechanism for diggingpotatoes, whereby the plow and revolving sifting cage are placeddirectly under control of the operator, and the plow-frame serves asasupport for one end ofthe cage,

The object of my invention I accomplish in the manner and by the meanshereinafter described and claimed, reference being made to theaccompanying drawings, in which- Figure 1 is a side elevation of apotato-digger embodying' my invention, the swinging frame being shown inits elevated position. Fig. 2 is a plan view thereof. Fig. 3 is acentral transverse cross-scction of the plow.

Similar letters indicate corresponding parts.

In the drawings, the letter A desi-gnates the axle of the potato-digger.

B B are the wheels journaled to the axle, and O is the draft pole, whichis rigidly secured to the axle, all constituting an ordinary` wheeledtruck.

D is a supporting-frame, to which is rigidly secured the plow E, which,in the example shown in the drawings,` consists of a circular frame, E',anda share or nose, E", projecting therefrom, the said share or nosebeing made of wrought-iron or steel, while the circular frame can bemade of cast-iron, the two being bolted together in the usual manner.

F is the sifting-cage, which is open at both ends, and is supported atits discharge endy upon rollers g, having bearings in a segment, G,extending across and attached to the frame, the said segment being adjustably secured in regard to height in order that the sifting-cage F canbe more or less inclined to the horizontal plane. rllhis adjustment canbe accomplished by casting the segment G- with projecting plates gi,having vertical slots g2, Fig. l, therein, which are engaged by boltsg3, eX- tending through the supporting-frame D, or by other well-knownmeans.

Selial No. 179,947. (No model.)

At its receiving end the sifti-ngcage F is supported upon rollers f,journaled in the circular frame of the digger-share, the said cage beingprovided at both its ends with suitableomitted, and that the diameter ofthe ring is somewhat larger than that ot' the circular frame F', whichis neessary to allow the cage to be shifted obliquely, as before stated,and as it is also desirable to have the lower portion of the peripheryof the ring f to bear closely against the circumference of the circularframe E.

The digger-share is secured to the supporting frame by means of arms e eextending therefrom, which latter are bolted to the frame at c2 e, androtary motion is imparted to the sittingcage from one of the wheels Bbymeans ot'a chain-wheel, b, secured to the one of the wheels whichconnects with a chain-wheel, b', having a common shaft with abevel-gear, b2, which engages with a bevelgear, b, on the cage.However', other means commonly employed for similar purposes can beadopted.

In order that the operatormay have perfect control of the plow-that isto say, in order that he may regulate the depth to which the shareenters the ground, or that the same, together with the cage, may beraised clear of the ground-I place the swinging frame subject to theaction of certain levers, which are actuated by the operator to producethe desired result. It will be observed that for this purpose twomotions of the swinging frame D, from which the share and cage aresuspended, are necessary-namely, a nearly parallel motion upward, whichwill eventually clear the plow entirely from the ground, andalsoatilting motionabout the axle A,which will properly incline thedigger-share.

The upward nearly parallel movement of the swinging frame D isaccomplished as follows: Near the forward end of the swinging IOO axleA, and the arms jj thereof are connected by chains jl jt, Fig. 1, toarms k 7c, extending outward from a shaft, K, having a bearing in ablock secured to the pole C, and which shaft K is turned by ahand-lever, L, extending therefrom and engaging with a tooth-segment,L,which latter retains the lever in any desired position. As shown inthe drawings, the lever L is in a position corresponding to the extremeelevated position of the supporting-frame, in which position the plow isen* tirely clear of the ground.A By shifting thelever in the properdirection the frame can be lowered until it bears upon the axle, asshown by dotted lilies in Fig. 1,or the plowshare can be retained in anydesired horizontal plane by the proper adjustment of the arm.

' To cause the plowshare to enter the ground to a greater or lessdegree, the frame is tilted about the axles by the action of ahand-lever, M, pivoted at m to the pole, and which is connected with theforward end of the frame by a link, N, pivoted to the supporting-frameand lever, so that by moving the lever in the properdirection the frameis caused to turn about the axle A as a fulcrum, whereby the plow isinclined. To retain the frame in the tilted position, the lever issubjected to theaction of a spring, m, which causes the same to engagewith one of the notches in a notched segment, M, secured to the pole Ain the proper position. Vhen the lever M is depressed while the frame isin anv elevated position, the frame then swivels about the fulcrum ofleverJ as a fulcrum, and the same effect is produced.

The object of my present invention is to obtain a potatodigger in whichthe position of the plow is directly under the control of the operator,and one in which such operation can be performed quickly and withbut-little exertion by the operator, while at the same time this diggeris characterized by its simplicity of construction.

It must be observed that since the circular frame of the plow extendsdirectly into the cage a smooth and continuous passage is formed for thetubers and the clod dug up by the plow, and there can be no possibilityof either potatoes or elod falling between cage and plow as in theordinary potato-diggers provided with siftingcages- VVhat-I claim asnew, and desire to secure by Letters Patent, is-

1. The combination, in a potatodigger, of the rotary siftingcage with aplow constructed with a circular frame extending into and supporting thefront end of the rotating cage, substantially as described.

2. The combination, in a potatodigger, of a rotating sifting-cage,havingan annular flange at its front end, with a plow constructed with anannular frame provided at its top portion I with friction-rollers, andextending into and supporting the flanged end of the rotating cage,substantially as described.

4 3. The combination, in a potato-digger, of a wheeled frame, asegmental frame at the rear thereof, a plow arranged at the front andconstructed with a circular frame, and a revolving sifting-cage, havingannular end flanges, respectively supported by and revolving on thecircular frame of the plowand the segmental frame, substantially asdescribed.

, 4. The combination, in a potato-digger, of a wheeled frame, asegmental frame at the rear thereof provided with friction-rollers, aplow arranged at the front and constructed with a circular frame,carrying friction-rollers, and a rotating sifting-cage, having endiianges supported by and revolving on said rollers, substantially asdescribed.

5. The combination, in a potatodigger, of a wheeled frame, a plowconstructed with a cir cular frame, arms secured to the wheeled frameand to the circular frame for suspend ing the plow, and a rotatingsiftingcage, having its forward end supported by and rotating on thecircular frame of the plow, substantially as described.

6. The combination, in a lLiotato-digger, of

the wheeled axle, the main frame capable of rising and falling bodilyindependent of the axle and to rest and tilt upon said axle, with a plowcarried by the frame, and a rotating sifting-cage, supported at one endby the frame of the plow. substantially as described.

7. The combination, in a potato-digger, of a wheeled frame, a segmentalframe vertically adjustable at the rear of said wheeled frame, a plowcarried by the wheeled frame and having a circular frame, and a rotatingsifting-cage, supported at its front end by saidv plow-frame and at itsrear end carried by and movable vertically with the segmental frame,substantially as described. l

8. The combination, in apotato-digger, of a wheeled axle, a main framecapable of rising and falling bodily independent of the axle and to restand tilt upon the latter, with the draft-tongue carrying a cross-bar,links pivoted at one end to the frame and at the other end to thecross-bar, levers fulcrumed between their ends to said frame behind thelinks and having their rear ends resting on the axles, handleversconnected, respectively,with the forward end of the frame and with the1e- Vers on the latter, the plow, and the sifting' cage, substantiallyas described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
